Over the past few years, I have had issues with my car shutting off when at a stop after the auto off feature engages and does not turn back on. I have to put the car in park and manually restart the engine to continue. This was happening at least a couple times a month. I took it to the Honda dealer and no problem was found according to the dealer. I began to get in the habit of disabling the auto off feature every time I started the car and this seemed to avoid this problem I was having. Two days ago, however, when I was driving, it began to shut off every time I was idling at a red light (8 times in one day) even with the auto-off disabled. And when I got on the freeway, driving at about 55mph, the engine shut off and I had to emergently coast over past the fast lane into a narrow inside shoulder. I had my young children and elderly parents in the car and it was a very scary and dangerous experience for us. We were thankful able to restart the car and get off the freeway with the car shutting off two more times in the middle of the street while driving at slow speeds (10-20 mph) before arriving at a gas station parking lot. The display cycled through many error messages ie emission systems problem, power steering system problem, transmission system problem, emissions system problem, hill start assist problem, etc. I am very concerned that we have got continued to have problems with this vehicle shutting off which is very dangerous.

The auto shut turns the car off at a stop light and then the car will not restart. It usually needs a jump. The problem has been happening for three years in the winter. The battery has been replaced four times. I have traced to the issue to an overload of the electrical system. The alternator is not capable of pouring all of the devices in the car and thus the battery drains. If I run the heated seats and steering wheel, the battery will discharge within 30 minutes even if the car is driven at highway speeds. I have been stalled in the middle of intersections several times. The autostart feature needs to have the option to stay dis-engaged when the car is shut off. It is unsafe to have the car fails to start at stoplights or when trying to pull into traffic. The electrical system is designed improperly. Do the math. The load from the electrical accessories, two heated front seats, two rear heated seats, heated steering wheel, heated mirrors, heated rear windshield will easily overload the power of a standard alternator. The vehicle needs a larger alternator and a larger battery (maybe dual) with isolation so it can start at stoplights.

At 38000 miles vehicle displayed an error code relating to the keyless start. A week later the vehicle would not start. Unhooked the battery to reset the system and the error came back. Dealer replaced the start button but issue returned a few days later.

We have an ongoing issue with our auto-idle feature malfunctioning that began at about 20,000 miles. I have written a complaint here before, as have many other 2016 Pilot owners, however nothing appears to have been done to date. This is a significant safety feature when the auto-idle is engaged, foot is taken off the brake and the car completely shuts off, often times not starting back up without a jump start. The car completely shuts off, warning lights flash all over the dash and no matter what you try the car will not start back up.this has happened to my wife with our 2 daughters numerous times. Fortunately, there hasn't been an accident, but my greatest fear is one time there will be. Naturally this always seems to happen at busy intersections. We have taken the vehicle into Honda dealership where we purchased the vehicle too many times to count. They have replaced the battery, replaced the start/stop switch, cleaned out multiple error codes. Nothing has provided a permanent fix. We just had to have our transmission replaced at 70,000 miles! the problem reared it's head again today. This time my wife had to press the brake, the gas pedal (both with all her might) and press the start/stop button at the same time. Something isn't right. I'm convinced we have a lemon, however the dealer seems to think we don't have a case for that. Honda has to step in and take accountability. There are far too many 2016 Pilot owners having this same issue for Honda not to realize the valid safety concern we all have. Take a look at piloteers.org and you will find a ridiculously long list of frustrated 2016 Pilot owners all struggling with the same problem. I am urging you to take action to correct this problem. We purchased this vehicle for the safety features, however "safe" isn't something I feel knowing my wife and daughters are in this vehicle multiple times per day.

The auto shut off feature turned the engine off at a red light - and would not turn the car back on once the brake was released. We needed to jump the Pilot to get it to turn over again. As this happened at an intersection on a state highway, we were very lucky to not be rear-ended! very unsafe and the mechanic said there is nothing wrong with battery!!

Persistent keyless start system problem and auto lock feature has stopped working.

- Goodyear, AZ, USA

Problem with the auto stop/start feature- the engine stops but doesn't always start. It tries to start but doesn't. pressing the start button (ignition) doesn't always work right away. Seams you have to put the transmission in park, and press the start button (sometimes 4-5 times) before the engine starts. This is nerve racking and dangerous when you are in traffic- say at a light, or trying to cross over oncoming traffic. The time is takes sometimes to re-start the engine is about 10-15 seconds. This problem is intermittent. (doesn't always happen). It's not the battery. I had a new battery replacement. I also tried using a trickle charger to "top off" the battery incase it wasn't fully charged. No luck.

The contact owns a 2016 Honda Pilot. The contact stated that on several occasions while at an intersection or stopped, the vehicle failed to switch to auto-start mode and the vehicle stalled without warning. The contact stated that the vehicle hesitated to accelerate for several seconds. While the vehicle was in reverse, the taillights failed to illuminate. The vehicle was taken to Honda of downtown los angeles (780 w martin luther king jr blvd, los angeles, ca 90037, (213) 266-7366) where it was diagnosed that the PCM needed to be reprogrammed and the battery was draining power. The vehicle was repaired however, the failure recurred. The contact mentioned NHTSA campaign number: 15V668000 (electrical system) as a possible solution to the failure however, the VIN was not included. The manufacturer was notified of the failure and informed the contact that the VIN was not under recall. The failure mileage was approximately 35,383.

Keyless start system problem error. Intermittent for months. Not present when taken to dealership twice. Scheduled service again next week was told by dealership it would cost $134 per hour to diagnose issue. Walk away auto lock no longer functions trunk hatch intermittently does not power open or closed. I have read hundreds of similar complaints with this make and model so I am very disappointed in Honda for not issuing a recall.

Car is parked in my garage. Car will not start. Remote keyless start error. Called the Honda dealer. They said to have it towed in. Waiting on the tow truck right now.

When turned off, car makes clicking noises while dash indicator lights and cabin lights flicker intermittently. Often I get a keyless start system problem error message. Other times just lights and clicking noises. Also, horn sounds intermittently throughout the day while car is locked and fob is untouched. Horn begins and stops randomly. This occurs when vehicle is turned off, in both parking lots and garage. Took to dealership. They did not know what it was. It has continued for several months.

There are two major problems, but the dangerous one is the auto-idle doesn't always allow the car to restart. When I go into idle at a stop sign or red light and I start to accelerat, all of the lights inside shut off and the car stalls after a foot or two. So far it has always managed to restart itself, but I've started turning it off whenever I get into the car because this is dangerous. This has been going on for months and it has only gotten worse (it probably started a year ago). At the same time this has happened, I got a "keyless ignition problem" warning light. The walk away lock feature doesn't work anymore. I've read numerous reports that say fixing the keyless switch doesn't help with the auto idle and there's no specific error code for issues with the auto idle system.

The automatic start system turns the car off and on when stopped at a red light or stop sign for example. The feature sometimes without any warning fails to restart the car automatically. The driver must put the car in park, push down on the brake, restart the car and then shift into park taking a considerable amount of time. This is dangerous for so many reasons and it must manually be turned off because it defaults to on. With no warning your car could be turned off and not automatically start when it's supposed to. This has happened to me multiple times stopped at red light, stop signs and in stop and go traffic. I would like to either have a warning in place or be able to permanently disable this dangerous feature.

Keyless start system error. Car have been showing this error intermittently. Replaced batteries and still shows error. When I pressed the button to start or turn off my car, it doesn't recognize it and it takes a few presses before it'll start/turn off my car.

Keyless start system problem

- Brentwood, NY, USA

Check engine light (cel) appears, randomly when parked or in motion, indicating a problem with emissions system. Cel began to appear at approximately 77,000 miles. Car now has over 85,000 miles. I purchased the vehicle used, when it had 68,000 miles. I have never driven outside of the U.S.. cel appears at various speeds between 0 and 60 mph. When in motion and cel is displayed, engine hesitation occurs causing me to increase vehicle speed and engine RPM to ensure I have sufficient power to: Complete a turn, pass another vehicle, or make it up a hill. I am never sure I will have enough power. Additionally, the mileage economy display changes from shades of green to solid white. Cel remains visible on dashboard until it randomly disappears. Cel will remain lit ranging from 30 minutes to several days and disappear at various speeds. When it disappears, engine hesitation stops and economy display returns to shades of green depending on whether accelerating or decelerating. I first believed it to be a problem with the fuel tank cap. However, the cap is a hinged flap that returns to the closed position after I have finished refueling. I predominantly use E87 octane with ethanol. But E89 fuel makes no difference because the cel and hesitation randomly still occur. I have not taken to a repair shop because I have not had the opportunity to when the cel is displayed. The repair shop stated they can only diagnose when the cel is displayed.

Keep encountering keyless remote start problem. Problem does not resolve. Takes several tries to get car started.

- El Paso, TX, USA

Engine light displays and warning message reads keyless start system error. I've replaced the batteries on both key fobs and it did not resolve the issue. No other issues at this time. Warning lights has displayed for about the last 1,000 miles. The alert did disappear for about 50 miles and returned.

When the car is started, dashboard displays message "keyless start system problem." This is being reported frequently on the internet and appears to be a common problem for this vehicle. When it occurs, the automatic walk away door lock feature also quits working. Supposed fix is to replace the start/stop switch which I did. This resolved the dashboard error message but not the automatic lock issue. This same result is being reported frequently on the internet and the problem is being reported for Honda Pilot beginning with the 2016 model and continuing up to the 2021 model.
